Description

Technical Field

[0001] This invention relates to the field of stator processing and manufacturing technology, specifically to a flat wire flaring device. Background Technology

[0002] In the manufacturing of high-efficiency, high-power-density motors, such as new energy drive motors, flat wire stator windings have become the mainstream technology due to their advantages such as high slot fill factor, excellent heat dissipation performance, and low DC loss. During stator winding manufacturing, flaring (or "PIN flaring") is a crucial process. Its purpose is to precisely widen and position the ends of the copper wires (PIN wires) at the welding end to facilitate subsequent insertion, twisting, and welding. The precision and reliability of this process directly determine the quality and consistency of the winding's electrical connections and the final performance of the motor.

[0003] Currently, most flat wire stator flaring equipment in the industry has adopted automated servo control systems to replace traditional manual or simple mechanical operations. These machines come in various forms, from simple models with a single gripper operating independently to high-efficiency models employing multiple flaring mechanisms (e.g., 6, 8, 12, or even more) operating simultaneously, and are widely used. However, in practice, insufficient flaring accuracy, especially in terms of circumferential positioning accuracy and consistency, has become a common bottleneck restricting the improvement of process quality and efficiency.

[0004] To address the issue of synchronous positioning of multiple grippers on a circumference, a typical existing method involves using a slotted, waist-shaped groove in conjunction with a circumferential reference for positioning. While this method is relatively simple in structure, it has significant drawbacks: First, the slotted groove requires a certain amount of radial movement, resulting in a less compact overall equipment structure and increased space requirements. Second, this positioning method has limited accuracy and rigidity. Even slight deviations in circumferential positioning can easily lead to uneven force distribution among the grippers during clamping and flaring. This uneven force distribution poses a dual risk: on the one hand, it may damage the insulation layer of the copper wire (PIN wire) or deform the conductor, affecting electrical performance; on the other hand, it may cause incomplete flaring or inconsistent openings at the wire ends, severely interfering with the smooth operation of subsequent stages (such as automatic wire insertion), and even leading to downtime and product scrap, impacting production cycle time and product yield.

Detailed Implementation

[0023] Reference Figure 1 The present invention proposes a flat wire flaring device, comprising: a rotating unit 10 and a gripper unit 20.

[0024] Reference Figure 2The rotating unit 10 includes an indexing plate 101, a turntable 102, and a support base 103. The support base 103 includes a vertically arranged rotating cylindrical body and a support plate located outside the rotating cylindrical body and fixed thereto. Both the indexing plate 101 and the turntable 102 are annular discs with a central opening. The indexing plate 101 is located on the inner side and is directly fixed to the top of the rotating cylindrical body of the support base 103 by bolts (or welding or other fixing methods), ensuring that the two are coaxial and form a stationary reference component. The turntable 102 is fitted around the periphery of the indexing plate 101 and is rotatably assembled with the rotating cylindrical body of the support base 103, thus allowing it to rotate freely about its axis relative to the stationary indexing plate 101.

[0025] Reference Figure 3 On the surface of the turntable 102, multiple identical Archimedean spiral guide grooves 1021 are uniformly machined around its center of rotation. All Archimedean spiral guide grooves 1021 are designed and machined with the center of rotation of the turntable 102 (i.e., the axis of rotation) as their pole, and their geometry follows the polar coordinate equation of the Archimedean spiral: This ensures that each guide groove is a spiral that expands uniformly outward from the pole.

[0026] The gripper units 20 are configured in multiples (e.g., 9) to directly perform the action of gripping the PIN wire. Each gripper unit 20 is evenly arranged circumferentially above the indexing plate 101 and is mounted radially on the indexing plate 101 via linear guides or sliding groove structures. Each gripper unit 20 is fixedly mounted with a drive bearing 20-0, which is rolled and nested within a corresponding Archimedean spiral guide groove 1021 on the turntable 102. The outer surface of each drive bearing 20-0 remains in contact with the two opposite sidewalls of the Archimedean spiral guide groove 1021, thus being effectively constrained by the groove. When an external drive component drives the turntable 102 to rotate around its axis, the gripper units 20, constrained by the indexing plate 101, can only move radially. The sidewalls of the Archimedean spiral guide grooves 1021 on the turntable 102 then push the drive bearings 20-0 in contact with them. Under the geometric constraints of the Archimedes spiral guide groove 1021, all the rolling nested drive bearings 20-0 will synchronously generate radial displacement, thereby equidistantly and synchronously pushing all the gripper units 20 to move radially inward (clamping) or outward (releasing) along the indexing plate 101, realizing synchronous drive control of multi-station grippers. Compared with the prior art, this has the following advantages: 1. By utilizing the Archimedes spiral guide grooves 1021 evenly distributed on the turntable 102, the rotational motion of the turntable 102 is synchronously and accurately converted into the radial linear motion of all gripper units 20, thereby achieving high trajectory consistency and predictability under mechanical forced guidance.

[0027] 2. All guide slots are based on the rotation center of turntable 102 as the pole point, ensuring that each drive bearing 20-0 moves synchronously under the constraint of the slot, so that all gripper units 20 move strictly in the same direction, thereby ensuring a high degree of symmetry and concentricity of the force applied to the PIN wire during the flaring or closing process.

[0028] 3. Since the guide groove and the drive bearing 20-0 form a closed force flow, the radial driving force always points to the center, which can effectively suppress the lateral force, reduce vibration, and enable the gripper unit 20 to maintain stable movement under high speed or high load conditions.

[0029] 4. This equipment only needs to rotate the rotary disk 102 to drive all gripper units 20 to move synchronously, thereby realizing centralized power distribution, simplifying the control system and reducing the complexity of multi-axis synchronization.

[0030] 5. The equipment achieves complex motion synchronization with a purely mechanical structure, and is characterized by its robustness, durability, and strong anti-interference ability. Wear is mainly concentrated on the contact surface between the guide groove 1021 and the drive bearing 20-0, which facilitates monitoring and maintenance.

[0031] As a further embodiment of the present invention, on the inner side of the indexing plate 101, below the workstation corresponding to each gripper unit 20, a cable fixing bracket 104 corresponding to that gripper unit 20 is provided; the cable fixing bracket 104 is fixed to the rotary cylindrical body of the indexing plate 101 or the support base 103, and the cable fixing bracket 104 is provided with a slot, and the slot opening direction is facing the axis of the indexing plate 101. The slot can accurately guide and position the wire harness, avoiding wire harness tangling or mutual interference.

[0032] As a further embodiment of the present invention, the present invention also includes a first drive unit 30 for driving the turntable 102 to rotate; the first drive unit 30 is mounted on a support plate of the support base 103, and includes a first servo motor 301, a lead screw 302 driven to rotate by the first servo motor 301, and a slide 303 threadedly engaged with the lead screw 302 and moving linearly with the lead screw 302; the support plate is provided with a linear rail 1021 arranged in the same direction as the lead screw 302 below the lead screw 302, the lower end of the slide 303 is slidably engaged with the linear rail 1021, and a groove perpendicular to its direction of movement is provided on the slide 303, and a second drive bearing 304 is provided in the groove. The outer circular surface of the second drive bearing 304 is in contact with the two opposite sidewalls of the groove to achieve guidance. The inner ring of the second drive bearing 304 is connected to a connecting shaft, and the connecting shaft is fixedly connected to the turntable 102 to convert the linear motion of the slide 303 into the rotational motion of the turntable 102. This structural design converts the rotary motion of the first servo motor 301 into precise linear motion by driving the slide block 303 through the lead screw 302. Furthermore, the linear motion is converted into the rotary motion of the turntable 102 through the cooperation of the slide groove and the drive bearing 304. This design ensures high precision and stability while enhancing the overall structural compactness, resulting in less wear and easier maintenance. Combined with the guidance and support of the linear rail 1021, it effectively reduces swaying during movement, significantly improving positioning accuracy, operational smoothness, and load capacity.

[0033] As a further embodiment of the present invention, it also includes a support base 40 and a cross roller bearing 50 and a second drive unit 60 mounted on the support base 40; the rotating unit 10 is disposed on the cross roller bearing 50 and its rotational support is realized via a cross ball bearing (preferred embodiment: the inner ring of the cross ball bearing is fixed to the support base 40; the rotating unit 10 is fixed to the outer ring of the cross ball bearing); the second drive unit 60 includes a second servo motor 601, which is connected to the rotating unit 10 through a crank 603 transmission mechanism to drive the rotating unit 10 to rotate. Specifically, the crank 603 transmission mechanism includes a connecting member 602 and a crank 603; the connecting member 602 is disposed on the rotating unit 600. The unit 10 is radially outward and rigidly connected to it (preferably, the connector 602 is fixed to the support base 103 of the rotating unit 10), and the connector 602 is machined with a guide hole extending radially; the crank 603 includes an intermediate connecting rod and a first end rod and a second end rod respectively disposed at both ends of the intermediate connecting rod and extending in opposite directions; the crank 603 is disposed below the connector 602, wherein the first end rod and the second end rod are both arranged vertically, the first end rod is drivenly connected to the output shaft of the second servo motor 601, and the second end rod is provided with a drive bearing 6031, which is clearance-fitted into the guide hole of the connector 602 and keeps in contact with the two opposing inner wall surfaces of the guide hole to form a radial guiding constraint. This structure replaces the traditional gear transmission with a crank 603 transmission mechanism. Torque transmission and radial guidance constraint are achieved through the clearance fit between the drive bearing 6031 and the radial guide hole. Combined with the cross roller bearing 50, it provides high load-bearing capacity, ensuring uniformity and smoothness of transmission. It effectively avoids the problems of uneven force, wear and clearance of traditional gear transmission, thereby improving rotational accuracy, motion smoothness and overall reliability. It is suitable for high-load and high-precision rotary positioning scenarios.

[0034] Reference Figure 4 The invention also includes a positioning sleeve 70, which is coaxially arranged with the indexing plate 101 and passes through the inner ring side of the crossed roller bearing 50, and is finally fixed to the support base 40. The top of the positioning sleeve 70 is provided with a wire distribution plate 701, which has a plurality of wire distribution grooves evenly opened along its circumference for guiding the PIN wires. The position of each PIN wire is guided and constrained by each wire distribution groove. This not only effectively prevents interference and ensures the reliability of the flaring process, but also provides convenience for subsequent clamping operations.

[0035] Furthermore, the distributor plate 701 and the positioning sleeve 70 are detachable. During operation, for different stator slot numbers and core specifications, only the corresponding distributor plate 701 needs to be replaced, which greatly shortens the changeover and debugging time and reduces the cost of special tooling.

[0036] Reference Figure 5The invention also includes a calibration fixture 80 for calibration and debugging. This fixture 80 is equipped with a simulated pin array to mimic the actual pin arrangement and can be detachably mounted on the top surface of the distribution panel 701. This design, by integrating a simulated pin array that can simulate the real pin and harness states onto the calibration fixture 80 and detachably mounting it on the top of the distribution panel 701, allows for efficient reproduction of production conditions during the debugging phase. It supports rapid calibration and adaptive adjustment of multiple mechanisms, thereby improving debugging efficiency and ensuring system coordination and operational reliability in subsequent formal production.

[0037] Reference Figure 6 The gripper unit 20 includes a carrier plate 201 and a clamping actuator 202 mounted on the carrier plate 201. The clamping actuator 202 employs a servo gripper or a cylinder gripper (preferably a cylinder gripper). The carrier plate 201 adopts a double-layer composite structure, including a lower base plate 2011 and an upper slide plate 2012 capable of linear displacement relative to the lower base plate 2011. The lower base plate 2011 is radially slidably assembled with the indexing plate 101 via a guide rail pair 205, and the movement trajectory of the upper slide plate 2012 is collinear with the guiding direction of the guide rail pair 205. A drive bearing 20-0 is disposed at the end of the guide rail pair 205 opposite to the indexing plate 101 and is rigidly connected to the lower base plate 2011 via a connecting shaft. The clamping actuator 202 is fixed on the upper slide plate 2012. The lower base plate 2011 is equipped with an adjustment assembly 206, which includes an adjustment rod 2061, a threaded rod 2062, a support block 2063, and a nut seat 2064. The adjustment rod 2061 is rotatably supported on the lower base plate 2011 via the support block 2063. The threaded rod 2062 is threadedly connected to and supported on the upper slide plate 2012 via the nut seat 2064, and the threaded rod 2062 is coaxial with and connected to the adjustment rod 2061. Through the cooperation of the double-layer composite carrier plate 201 and the adjustment assembly, rapid linear adjustment and precise locking of the gripper position are achieved, improving the equipment's adaptability to different types of stator flare spacing and its changeover efficiency.

[0038] Furthermore, the threaded rod 2062 and the adjusting rod 2061 are connected by a universal coupling 2065. This structural design effectively compensates for possible flatness and coaxiality deviations during installation and processing, improves assembly tolerance, and ensures the alignment accuracy and reliability of the transmission system.

[0039] Furthermore, a displacement display 203 is installed on the lower base plate 2011. The detection shaft or gear of the displacement display 203 is connected to the adjusting rod 2061, which can convert the rotation angle (number of revolutions) of the adjusting rod 2061 into a linear displacement and display it digitally in real time, so as to display the feed displacement of the adjusting rod 2061 in real time, thereby facilitating the operator to accurately adjust the position of the clamping actuator 202.

[0040] Furthermore, the guide rail pair 205 includes a guide rail and a slider that is slidably assembled with the guide rail; wherein, the guide rail is fixedly disposed on the bottom surface of the lower base plate 2011, and the slider is detachably fixedly connected to the indexing plate 101. This structure integrates the guide rail on the lower base plate 2011 and detachably mounts the slider 303 on the indexing plate 101, thereby reducing the overall radial dimension, while also possessing the advantages of good load-bearing stability and high precision retention, facilitating the quick assembly and disassembly of the indexing plate 101.

[0041] As can be seen from the above, this flat wire flaring device, by radially sliding the gripper unit 20 on the indexing plate 101 and rolling the drive bearing 20-0 within the Archimedean spiral guide groove 1021 evenly distributed around the turntable 102, utilizes the geometric characteristics of the Archimedean spiral to forcibly convert the circumferential motion into a radial linear motion with all gripper units 20 strictly synchronized and always pointing towards the center of the circle when the turntable 102 rotates. This fundamentally solves the problem of accuracy and synchronization in multi-gripper circumferential positioning, providing reliable equipment support for the large-scale, high-quality manufacturing of high-performance flat wire motors. Furthermore, by centrally controlling a single rotary drive source, the system structure and control complexity are simplified, and the stability and reliability of the equipment under high speed and high load are improved.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
